As for the Waldo movie, Berger had a good-natured sarcastic take on writing yet another screen adaptation of a plotless children’s property. “I’m working on the Where’s Waldo movie for MGM which is a really a movie that writes itself,” he joked, then confirmed, “I am being sarcastic, yes. It’s going to be an adventure but the plot we came up with I think is pretty clever, but legally I’m not allowed to talk about it. Once it’s introduced to the world I think people are going to be like, ‘Oh, that’s a good idea. I like that.’”
